(referenced patent document CN105026297B).
Summary of the invention
The present invention provides a kind of monitoring systems of elevator cable, stress condition and multinomial big number in conjunction with cable
According to the synthetically safety of evaluation cable guarantees that elevator is reliablely and stablely run in order to prevent elevator cable breaks.
The elevator includes the rack plate for fixed cable for being installed on car top；
The monitoring system includes:
Circular photo resistance is fixed on the first cable above rack plate；
Laser emitter, second adjacent with the first cable being oppositely disposed with photo resistance above rack plate
On cable, for emitting laser to photo resistance, in the initial state, the central area of the laser alignment photo resistance, this
When photo resistance resistance value be the first value；
Ohmer is fixed on rack plate, for detecting the change in resistance of photo resistance；
Further include:
Frequency of use detection device is arranged in the key box outside cage door, for detecting and counting elevator
Frequency of use comprising two pressure sensors and a statistic unit, wherein pressure sensor be respectively arranged above and below by
The rear of key, for detecting whether key is pressed, this key when the pressure value of pressure sensor is greater than first predetermined value
It is pressed, when the pressure value of pressure sensor is less than first predetermined value, this key is not pressed；Statistic unit is for counting
And the number data that the key in the first period outside elevator is pressed are stored, the number data make with the elevator
It is positively correlated with frequency；
Controller, signal are connected to ohmer and statistic unit, when ohmer detects that the resistance value of photo resistance differs
When the first value, show that cable due to discontinuity, causes laser emitter and photo resistance on adjacent cable to produce
More than the relative displacement of zone of reasonableness, so that the light beam for being directed at annular photo resistance central area in the initial state occurs
Offset, at this point, controller judge that the safe-use period of cable is limited to the first validity period, and from statistic unit second period of acquisition
The interior number data show the frequency of use height namely cable of elevator when the number data are higher than first threshold
Friction between rope groove is more frequent, so that the risk of cable abrasion increases, therefore, controller judges the peace of cable
Entirely using the time limit by the first validity period shorten to the second validity period, and when the number data are lower than first threshold, controller is sentenced
The safe handling time limit of disconnected cable is still the first validity period.
Wherein, the first period was preferably one month, and the second period was preferably one week.
The beneficial effects of the present invention are: comprehensive in conjunction with the frequency of use situation of cable unbalance stress and elevator in one week
It evaluates the safety of cable with closing, in order to which maintenance personal repairs according to judging result in due course, avoids overhauling because of cable too late
When and cause elevator to break down, to prevent elevator cable breaks, guarantee that elevator is reliablely and stablely run.
